Using ntlm and MS-CHAP authentication on the same server

Hi to all, I would like know if it is possible to configure the Freeradius to do authentication based on ntlm for one group of users and MS-Chap for other on the same server. In my configuration I use one radius server for controling access to wireless network and dial-up network. The problem is that I do not want users from one group to get logging in sistem using credintials from other. Does anyone any ideas?
